    How to control corn borer?
     
    1. Agricultural control
    Get rid of corn stalks and leaves after harvesting, smash them into pieces and bury the pieces into the soil to kill overwintering larva corn borers.
     
    2. Biological control
     
    Release the first batch of trichogramma wasps to the fields at about the eleventh day after overwintering larvae hatching rate reaches 20% -30%, and then release again in every 4 -5 days. Be sure to release 90,000 - 180,000 trichogramma wasps per acres.
     
    3. Physical control
     
    1). Use frequency-vibrancy or solar insect killing lamp to attract and kill adult corn borers. Place 1 or 2 lamps in every 10 acres and keep each of them at a distance of 100 meters. Hang them at 1 meter higher than the crops. And remember to clear insect bag regularly and keep the lamp in good conditions to improve insect-control effect.
     
    2). place one piece of sex pheromone for corn borer in every 50 meters in a 20cm diameter basin filled with liquid detergent. The basin should be a little higher than the corns, and remember to fetch out the borers, refill the basin with water and detergent.
     
    4. Pesticide control
     
    Use pesticide as a last resort to control corn borers.
